DENSITY TRIANGLE???

The density triangle is a trick that will tell which formula to use in order to find the density, mass, or volume when you have the other two.

What does it look like?

The density triangle is a triangle that is split into three sections. 

• Density, which is symbolized by the letter "D," is in the left bottom section
• Mass, which is symbolized by the letter "M," is on the top
• Volume, which is symbolized by the letter "V", is on the bottom right.

Write the letters D, M, and V in the triangle in the order that you reach each section as you go from left to right. The diagram below will show you how this is done.

How do we use it?

To use the DMV Triangle, after you have set it up, simply cover the item that you want to find and you have to formula!!! Below are a few demonstrations.

Start with the DMV Triangle:

To find the formula for "Density," cover up the "D" (as shown below).

This leaves the the "M" over the "V," giving you the formula "M/V." Therefore, the fomula is D = M/V
To find the formula for "Volume," cover up the "V" (as shown below).

This leaves the the "M" over the "D," giving you the formula "M/D." Therefore, the formula is V = M/D.
To find the formula for "Mass," cover up the "M" (as shown below).


This leaves the the "D" over the "V," giving you the formula "D x V."  Therefore, the formula is M = D x V.

Why would we want to use this?

By using this trick, you never have to remember any of the actual formulas. All you have to do is remember "DMV." Since the Department of Motor Vehicles. The trick is knowing where each letter goes, but, once you have that down, each of the formulas can be seen easily, without a chance of error.
